A creation for the HCMaker 7 AKA Imagine That 3d Helios - CR-10 direct drive clone. Parts: Two additional fans are required: a 30MM Fan and a 40MM Fan. Optional: Three fan variation includes an aluminum Heat Sink for stepper motor with a hole in the middle. Remove the existing plastic cooling system entirely. Further parts include m3 screws, with a complete detailed list to come after assembly installation. Screws: Two Flat head Metric 10MM screws are used to hold the 30MM fan on, with a smaller profile providing better results. Ten M4-10MM metric screws are used for all other parts. Eight screws will hold the fan in place, four of which secure the Note that holes may need to be drilled for easier threading.
